RACK FOR HANDL'ING LOCOMOTIVE CABS Fileq April 2, 1930 Patented July 28, 1931 CLAIR nnrnomrsoiv, or Los ANGELES, cAuronNrA RACK FOR HANDLING LOCOMOTIVE CABS Application filed April 2, 1930. Serial' No. 440,981.

My invention pertains to a rack which is especially adapted to handle locomotive cabs when it is desired to shift. the cabs after removal from the locomotive, from one place '5' to another. The rack is shaped to engage the sills of the cab and an elevator truck may be backed underneath the rack and then utilized to liftthe rack with the cab and shifted to' the desired place for any work that may be in hand. If desired then, the cab may be supported on blocking and the elevator truck with the rack lowered; thus removing the rack. i I r A feature of my invention is the construc- 'tionof a rack with comparatively low side marginal portions and an elevated center portion. shoes to bear on thefioorof the shop and the center portion is 0 rack on the table or platform of the lifting truck. Another feature, ofthe rack isthat the end portions are extensible and may be 7 shifted outwardly slightly to accommodate cabs of somewhat different widths. My invention is illustrated in connection with the accompanying drawings, in which,

Fig.1 is aside elevation showing the rack on an elevating truck with a locomotivecab indicated on the rack; I b Fig. 2vis .a plan of the rack taken in the direction of the arrow 20f Fig.3;

Fig.;.1 is an end elevation taken in the direction of the arrow ,4: of F igQ 2; Fig. 5 is adetail vertical sectionon the line 5-5 of Fig. 3 in the direction ofthe arrows. The major-portionofthe rack can be 0. made of material which is usually considered as scrap in railroad; yards and has as main structural elements, two main side beams 11. These are preferably formed of old steel rails and there .is atop section '12,' a sloping section 13 andmarginal sections a 14. Positioned below the center portion 12 ing rail '15, This iswelded or otherwise attached to the-sloping section 13. There are a pair of marginal lugs 16 secured to the The marginal side portions have constructed to centertlie of each rail there is a secondary or supportundersurface of the rails 15 and the space between these lugs is but slightly greater than the width of the platform on anele- 1 vating truck. 5

There are tie bars 17 extending between the rails, these being illustrated as through the upper section 12 adjacent the corners 'withthe section 13 at the junction line of the sections 13 and'14 and also tie bars;

through the rails 15. Secured underneath 0 v the rail sectionsl l there are a pair of le s 18, these being tubular, formed of pipe. it the bottom of the legs there are shoes 19 made of metal plates turned up at the ends.

These shoes give a relatively'large bearing e5v area andthe legs may be made-of different heights according to the general height of the rack above the ground.

, The'side extensions are made by having a slot 20in each ofthe rail sections 14 and 70.

on each side of these rails there are metal side straps 21 somewhat in the form of fish plates with a bridging strap 22 at the top. The bridging straps may be welded together and there is a bolt 23 extending through the side straps through the slot 20 so that the side straps with the bridging piece may-be slid outwardly or inwardly on the rail en'd sections 14;. Connecting these extensible portions there is 'a bolting I plate 2 1 secured to the outer endsof the slidable slide strap and bridging straps and extending'between the rails at opposite ends of the rack. 1 These are utilizedto support the sills of the locomotive cab and such sills s5 may be bolte'dto the plate 24:. v

The manner of using the rack may be considered substantially as follows: In railroad repair yards there is generally a cab to the cabs and 90.

department where repairs overhauling of such cabs is donesind'ependently'ofoverhauling and repairs to the lo comotive. A'lift'truck is utilizedto trans-v fer the cabs from the locomotive to the cab department. Such lift' truck may have its '95 platform lowered and-run underneath the i center part of the rack so that the platform of the truck when raised will engage thelower rail 15'With the lugs engaging opposite sides of'the platform and thus center .00

ing the rack. The platform of the truck is then raised and the rack is moved to a location near. a crane so that the locomotive cab may be lifted from the locomotive and placed on the rack. Before being placed on the rack the side extensions are moved outwardly and the cab is lowered, resting on these extensions. The truck may then convey thecab to the cab department and after positioning it in a suitable location, the cab is supported by blocking. The truck platform is then lowered, disengaging, the. ends.

of the rack from the cab and the extension ends are then thrust inwardly so that "the truck withthe rack thereon may be moved out. frpm underneath the cabytheblocking of the cab being attheonter sidepoi tions.

7 When it is desired to replace the cab on .,the ,,1ocomo tive, the, truck with the rack thereon andl the side extensions thrust in, is 111111.. underneaththe cab. The extensions are, pulled ont and the platform of the truck raised, thus lifting the caboff the blocking,

whence it. may be takenito a crane and hoisted onto the locomotive. Theside ex tensions, therefore facilitate removal of the red; from. a blocked up cab and also facilitate i'epla cingithe rack underneath the cab .on its ,blocking.' The blocl ings manifestly should be placed at theiside oi the cab so that when the extensions are drawn in they will clear the blocking, g

.Various changes maybe made in the prinaeiples of my] inventionwithout departing from the spirit thereof :as set forth in the description, drawings and claims.
